tudorziman Posted September 29, 2015 Report Posted September 29, 2015 hello, I'm new to PLC programming and this forum so I kindly ask for some help. I am designing a conveyor system that is driven by a motor and some pneumatic actions are generated by 2 limit switches. My questions are related to the ladder program to my CP1E PLC: 1) What is the best way to implement a Master Reset button function? 2) I want a coil to be activated after a limit switch is ON twice (the second time or even third ON event). Basically I want to skip one or two turn-ON events of the limit switch. What is the easiest way to do it? 3) I would also want to implement the program into a stateflow form. The events should come one after the other with control of the steps but only the Master Reset should stop the process but have the possibility to continue it from the same step after Reset is gone. Thank you.
